How many teaspoons are in 200 milliliters? 1 tsp = 5 ml 200 mL = [?] tsp

40

Step-by-step explanation:

using dimensional analysis ( you might not have learned this yet, but it's basically multiplying things to cancel out units)...

200 ml * (1 tsp/ 5 ml) = 40 tsp  

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

the answer is 175.4379
